まとめ
低線量CT(LDCT)を用いた肺がんスクリーニング(LCS)は、リスクの高い個人において死亡率を20%以上大幅に低下させる。AIとリスク予測における継続的な進歩は、早期発見と患者の転帰のさらなる改善を約束する。
科学分野:
- 呼吸器学;放射線学;腫瘍学
背景:
- 低線量コンピューテッドトモグラフィー(LDCT)による肺がんスクリーニング(LCS)は、肺がん死亡率を低下させる上で有効であることが証明されており、NLSTやNELSONなどの画期的な試験では20%以上の減少が示されています。LDCTは現在、リスクの高い集団における早期発見の標準治療となっており、13カ国が国または地域のスクリーニングプログラムを実施しています。
主な方法:
- 画期的な臨床試験(NLST、NELSON)およびLCSプログラムの現在の世界的実施のレビュー。結節検出とリスク評価におけるAIを含む最近の技術的進歩の分析。スクリーニングへのアクセス向上、患者エンゲージメント、禁煙および他の疾患検出との統合のための戦略の検討。
結論:
- 肺がんスクリーニングは肺がん制御の基盤であり、継続的なイノベーションは世界的な利益と公平性を最大化するために不可欠です。リスク層別化、画像技術、バイオマーカー統合における継続的な進歩は、LCSの進化に不可欠です。データ標準、品質指標、労働力トレーニングの調和は、LCSプログラムの持続的な高品質な実施に不可欠です。

mTOR Signaling and Cancer Progression
4.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Lung Capacity
56.4K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Social Foundations of Self I: Play and Game
223
The development of self in children is deeply rooted in social interactions, mainly through stages of play and structured games. These stages, outlined by sociologist George Herbert Mead, illustrate how children progressively learn to understand and adopt social roles, forming a cohesive sense of self.The Play Stage: Imitation and Simple Role-TakingIn the early years of childhood, the play stage is characterized by imitative behavior, where children engage in role-playing based on familiar...

Le Chatelier's Principle: Changing Concentration
66.0K
A system at equilibrium is in a state of dynamic balance, with forward and reverse reactions taking place at equal rates. If an equilibrium system is subjected to a change in conditions that affects these reaction rates differently (a stress), then the rates are no longer equal and the system is not at equilibrium. The system will subsequently experience a net reaction in the direction of a greater rate (a shift) that will re-establish the equilibrium. This phenomenon is summarized by Le...

Le Chatelier's Principle: Changing Volume (Pressure)
40.6K
For gas-phase equilibria, changes in the concentrations of reactants and products can occur with altered volume and pressure. The partial pressure, P, of an ideal gas is proportional to its molar concentration, M.

Global Climate Change
29.0K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
